Definitions
- the present invention relates to a safety switching device for safely stopping a machine system from who runs a risk with a first and a second Input switches, their respective switching positions simultaneously and redundantly define a manipulated variable on the input side, with at least one output switching element that is in an output circuit the safety switching device is arranged, and with an evaluation and control unit that depends on the defined manipulated variable, the at least one output switching element controls, the evaluation and control unit two channels is formed, wherein a first channel with the first input switch and a second channel with the second input switch is connected, and wherein switching contacts of the first and of the second input switch with regard to their switching position are coupled to one another via a common actuator.
- Such a safety switching device is from the applicant of the present invention under the type designation PNOZ XV2 distributed.
- Safety switching devices in the sense of the present Invention belong to both independent safety relays as well as complex safety controls, for example on the basis of a safe PLC control.
- Such devices are mainly used in the industrial area to switch operations to perform in a safe manner.
- "Safe" means in this context that the device at least meets category 3 of the European standard EN 954-1.
- such devices are used to in Reaction to the actuation of an emergency stop button or opening a protective door a machine system from which there is a danger going out, stopping or otherwise in a safe Convict state. Because device failure in one such situation is an immediate threat to people or also results in material values are considered the fail safety of safety switching devices very much high demands made. This leads to a lot of effort combined with high development and manufacturing costs of safety switching devices.
- the input side Manipulated variable is a time constant that is a delay time determined when switching off. Such a delay time is required, for example, to switch off a Machine system controls movable drives in one to be able to move to a safe resting position.
- the time constant is in the known safety switching device with the help set by two mutually redundant rotary switches that arranged one below the other or one behind the other on a common shaft are. This structure is described in more detail below with reference to FIG. 2 explained.
- the manipulated variable to be set can be used by everyone a safety switching device relevant input parameters his.
- the known safety switching device fulfills the safety requirements Requirements of the standard EN 954-1 in particular this is because the two input switches are separate from each other define the desired time constant. Due to the Resulting redundancy can be a fault on one of the switches reliably recognized by the evaluation and control unit become.
- the disadvantage is that the production of the known Safety switching device a high mechanical effort requires what is associated with correspondingly high costs.
- the structure of the known safety switching device is required comparatively much space, what a miniaturization generic devices prevented or at least difficult.
- Switch units known for many years in which by the actuation of an actuator perform two switching functions to let.
- a corresponding switch unit is, for example described in DE 25 45 719 A1.
- This task is performed in the safety switching device mentioned at the beginning solved in that the switching contacts of the first and second input switch spatially on one level are arranged and that the actuator is a common circular support member includes on which the switching contacts of the first and second input switch arranged radially offset from each other are.
- the switch contacts of the two are Input switch in the known safety switching device in two parallel planes. This has to Consequence that the two input switches in two separate Steps in the housing of the safety switching device must be installed.
- the two Input switch in the safety switching device according to the invention can be assembled in a single step. This simplifies assembly and the invention Safety switching device can be produced more cheaply become.
- the actuator contains a common one Carrier element on which the switching contacts of the first and second Input switch arranged spatially offset from each other are.
- This measure has the advantage that the switch contacts two input switches on structurally very simple and therefore inexpensive way are coupled. On couplings, Gearbox or other measures to transmit a shift movement from the first input switch to the second therefore be dispensed with without the risk of different Operator setting exists.
- this is common carrier element adjustable in rotation.
- the common carrier element may be translationally adjustable.
- design has an advantage above all if the two input switches multi-position switch are, since the existing switching contacts save space to each other and can thus be arranged in a more compact manner.
- the common carrier element is a carrier disc on which the switching contacts of the first and second input switches are arranged radially offset from one another.
- the two can be separated Input switch particularly small and space saving in be integrated into a common mechanical structure. moreover This also simplifies the assembly of the input switches in the housing of the safety switching device according to the invention.
- This measure has the advantage that the separate Input switch a common, redundant in itself Form component that is very simple and therefore inexpensive Way in the safety switching device according to the invention can be assembled. It also failsafe increased even further because of the risk of damage the redundant switch arrangement during assembly or at a later intervention in the safety switching device is reduced is. In addition, the safety-relevant switch arrangement in this way particularly good against external environmental influences, such as pollution. This also contributes to increasing error security.
- the switch contacts of the first and second input switch sliding contacts, with the help of the actuator via fixed contact surfaces are movable.
- the two input switches are on fail-safe Way even in very large numbers produce what minimizes the cost of the two input switches.
- the error measure further increases the reliability, since conductor track structures in the operation of the device are not subject to any wear or at most extremely little wear, so that a subsequent operation of the device occurring errors is largely excluded. Likewise the risk of subsequent cross-circuits or short-circuits reduced.
- the first and second input switches each multi-position switch.
- the first and second input switches on the input side and output side Connection contacts, each in a matrix structure to each other are arranged.
- This measure has the advantage that the number of required Connection contacts for the two input switches reduced can be, which is also a reduction in the required Space allows. It also simplifies thereby the assembly.
- This measure reduces the number of connections required reduced again for the two input switches. So this measure makes it possible, for example, to 16 each other redundant switch positions, i.e. a total of 32 switch positions, with only a total of 12 connection contacts. As a result, the space of the invention Arrangement reduced again and the assembly can be simplified.
